STOVE-GRATE.

Application filed October 6, 1913.

To all whom it may concern Be it known that I, ANNA STEINLY, citizen ofthe United States, residing at Mongo, in the county of Lagrange andState of Indiana, have invented certain new and useful Improvements inStove-Grates, of which the following is a specification.

The present invention relates to new and useful improvements in stovesand aims particularly to provide a novel and cfiicient form of gratewhich is hingedly mounted in the fire-box so that it may be swungdownwardly to effect the complete displacement of all ashes, cinders anddead coals during the act of cleaning out of the stove.

An object of equal importance with the foregoing is to equip the gratewith a guide chute which will operate to insure the passage of the ashesand cinders directly from the grate into a receiving pan, such as isordinarily removably disposed on the bottom of the fire-box. l

A still further object is to construct the grate and associatedmechanism with such regard to proportion, number and arrangement ofparts that they may be cheaply manufactured, will be durable andefficient in their action and may be quickly and conveniently applied toany standard form of stove with a minimum expenditure of time and laborand without requiring the disassembling of any of the parts of thestove.

The above and additional objects are accomplished by such means asareillustrated in the accompanying drawings, described in the followingspecification and then more particularly pointed out in the claims whichare appended hereto and form a part of this application.

\Vith reference to thedrawings, wherein I have illustrated the preferredembodiment of this invention, as it is reduced to practice, andthroughout the several views of which similar reference numerals designate corresponding parts: Figure 1 is aperspective view illustrating thegrate and associated structure in assembled position in the fire-box ofan ordinary cooking range, portions of the stove body being broken awayto clearly disclose the interior arrangement of the parts; Fig. 2 is avertical section taken through the fire-box; Fig. 3 is a detail view ofthe grate hinge-rod; and Fig. 4 is a perspective view illustrating' amodification of the preferred form of grate.

Specification of Letters Patent.

Patented Mar. 2, 1915.

Serial No. 793,633.

Proceeding now to the description of the drawings, the preferredembodiment of this invention includes a hinged grate l0 and a dischargechute 11. f

The grate 10 may be of any suitable type, although in practice is hasbeen found deenable to employ a grate of the bar type formed of castiron, as illustrated in the accompanying drawings. This grate carries onone longitudinal edge a hinge-rod 12 to which it may be secured bywelding or any other expedient, this invention comprehendlng, of course,the employment of collars and set-screws, or any other similar devices.The terminals of this hinge-rod 12 are journaled in alined aperturesformed in the end walls of the fire-box, the one terminal being formedwith an enlarged squared head 13 which is disposed exteriorly of thestove and is provided for thepurpose of permitting the application of awrench, or other similar tool, when it is desired to swing the gratefrom dependent open position to horizontal closed position, as will behereafter more fully disclosed.

As a means for supporting the grate in horizontal closed position and atthe same time permitting it to be readily released to drop intodependent position, as indicated by dotted lines in Fig. 2, there hasbeen pr0- vided a number of plunger pins 1-1 which extend in spacedrelation to each other and project laterally from a head-board 15. Thesepins 14 operate through spaced bores or apertures formed in the wall ofthe firebox and are normally heldwith their major portions disposedinteriorly of the fire-box through the medium of helical springs 16,which arewound around the pins and are interposed between the head-boardand the adjacent outer face of the fire-box wall having their oppositeterminals connected to the firebox and head-board.

From the foregoing it is of course obvious that when the operatordesires to release the grate it is only necessary to pull the head-boardaway from the wall'of, the fire-box with the resultant withdrawal of thepins from supporting engagement with the grate. When the grate isreleased, it will of course, swing downwardly. permitting the ashes andcinders to fall to the ash pan, conventionally illustrated at 17.'

As a means for insuring the complete deposit of ashes in the ash-pan,there has been provided a discharge chute, heretofore designated by thenumeral 11. This discharge chute consists essentially of a metalliccasing 18, the side and end walls 19 and 20 of which are downwardlyconvergent and obviously tend to deposit the falling debris to thecenter of the ash-pan. Bolts, rivets, or other suitable fasteningdevices, indicated at 21, may be employed in holding the discharge chutein the desired position within the lire-box.

In order to limit the downward movement of the grate, there has beenprovided a suitable arm 22 which is preferably formed of a strip ofstrap metal, one terminal of which is indicated at and is folded orotherwise secured to the wall of the fire-box. The major portion of themember 22 is inclined downwardly from the rear wall of the fire-boxtoward the front wall and is equipped at its free terminal with anangular projection 24 which engages the grate 10 and holds it againstfurther downward movement, as will be readily observed upon reference todotted lines in Fig. 2. It will be noted upon reference to this figurethat the angular portion 2-1: of the member 23 extends through a slotformed in the adjacent wall of the casing 18.

In the modification illustrated in Fig. 4, the grate is, as in thepreferred embodiment, equipped with a hinge rod 12 having a square head13, but differs in that its longitudinal edges are equipped withinwardly directed flanges 14: which extend in parallel spaced relationto the plane of the body of the grate, being adapted to receive aslidable plate 15 which is equipped with a handle 16.

l hen this modified form of grate is employed, a slot is formed in theend wall of the fire-box to permit the insertion or removal of the plate15. Relative to the func tion of this plate 15, it will be apparentthat, if the operator desires to shut off the draft from the combustionchamber for the pur pose of banking the fire, it is only necessary toinsert the plate 15 between the flange. 14 and the body of the gratewith the resultant sealing of the fire-box. It is obvious that, ifdesired, the plate may be inserted only part way, so that the heat will.be reduced or retained longer.

In conclusion, it is desirable to emphasize the fact that the grate andassociated structure are constructed in such manner that all liabilityof breakage or derangement of parts is obviated and that by merelywithdrawing the head-board in the manner above described, the operatormay quickly remove all the ashes, cinders, and the like from the grate.it is further to be observed that the deposit of all debris from thegrate into the ash-pan is insured by the provision of the dischargechute.

In the preferred embodiment of this invention there is provided an ash.receptacle which is illustrated in Figs. 1 and 2 and is designated bythe numeral 25. This ash receptacle is substantially rectangular inshape and formed with a closed top and bottom, being preferably formedof sheet metal or some other similar material. In the closure of thecasing is formed a rectangular opening 26 which is adapted to registerwith the lower end of the ash chute 18 when disposed in the bottom ofthe fire box in the usual receiving position. It will be noted that thisform of ash receptacle insures a complete deposit of all the ashes in arestricted area and that the entire deposit of ashes may be withdrawn bymerely removing the ash pan.

In reduction to practice, I have found that the form of my invention,illustrated in the drawings and referred to in the above description asthe preferred embodiment, is the most eflicient and practical; yetrealizing that the conditions concurrent with the adoption of my devicewill necessarily var y.

I desire to emphasize the fact that various minor changes in details ofconstruction, proportion and arrangement of parts may be resorted to,when required, without sacrificing any of the advantages of my invention, as defined in the appended claims.

Relative to the various modifications to which the present invention maybe subjected, it is desirable to direct attention to the fact that thedischarge chute 11 may be bolted flatly against the inner wall of thefire-box along its upper edge instead of being spaced away from thefire-box walls a .ligl t distance as shown in the drawings.

Having thus described the invention what is claimed as new is 1-- 1. Thecombination with a fuel burner, of a grate hingedly mounted in thecombustion chamber thereof, means for limiting the downward swingingmovement of the grate, and a supporting member for normally holding thegrate in horizontal position, said supporting member including aheadboard, a plurality of pins carried thereby and adapted to projectthrough the wall of the fire box for supporting the free edge of thegrate, and a plurality of helical springs wound about the pins andsecured at their terminals to the wall of the fire box and thehead-board, said springs being adapted to normally hold the pins insupporting relation to the grate.

2. The combination with a fuel burner, of a grate adapted to be hingedlymounted in the combustion chamber thereof, a hingerod carried by thegrate and journaled in the walls of the combustion chamber, a 7

squared head formed on one end of the hinge-rod and disposed exteriorlyof the combustion chamber, for the application of an operating tool, andmeans for supporting the grate in horizontal position, said meansincluding a plurality of plunger pins mounted for movement throughapertures formed in the walls of the combustion chamber, springs fornormally holding the inner ends of the plunger pins in supportingrelation to the grate, and a head-board connected to the plunger pinsand disposed exteriorly of the combustion chamber, whereby all the pinsmay be simultaneously withdrawn from supporting relation to the grate.

3. The combination with a fuel burner, of a grate hingedly mounted inthe combustion chamber thereof, means for normally supporting the gratein horizontal position, a

Copies of this patent niay be obtained for five cents each, byaddressing the Commissioner of Patents guide chute positioned in thecombustion chamber below the grate, and a stop arm secured to the wallof the combustion chamber and projecting into the chute, said stop armbeing formed of resilient strap metal and being adapted to limit thedownward swinging movement of the grate.

In testimony whereof I aflix my signature in presence of two witnesses.
